Australia's Soundwave Festival is typically one of the first major rock events of the year, and as the festival hits 15 years in business, it's still drawing the top names. Slipknot, Faith No More, Soundgarden and Slash are among the top-billed acts at the just-announced 2015 run.

Organizers are varying things up this year, making Soundwave a two-day music festival taking place over two weekends in four Australian cities. The lineups will just swap cities the day after they perform in one of the locations.

The following weekend, the Faith No More bill heads to Sydney on Feb. 28, while Brisbane gets the Slipknot lineup before the two bills switch cities on March 1.
